Abstract
For monitoring the state of a motor brake, the invention provides a method by means of which in a measuring sequence in speed-regulated operation, the brake is applied for a short time and over this time a motor current is measured and the brake torque determined on the basis of the thus obtained measuring data.
Claims11
Method for checking the brake of an electric motor, characterized in that in a measuring sequence in speed-regulated operation the brake is applied for a short time and at least during this time a motor current is measured and on the basis of measured data obtained in this way the brake torgue of the brake is determined.
